通过按钮单击禁用/启用按钮

Question

I am displaying SQL data in rows and each row contains "Add To Zip" Button.我在行中显示 SQL 数据，每行包含“添加到 Zip”按钮。 The button for each row is enabled.启用每一行的按钮。 I want to disable the current row's button on click.我想在点击时禁用当前行的按钮。 I later want to re-enable these disabled buttons through another button in a different php file.我稍后想通过不同 php 文件中的另一个按钮重新启用这些禁用的按钮。 How do I achieve this?我如何实现这一目标？ Also, please do not point to SQL injection, I have used login details to check if the correct credentials are added or not and I will be only posting the code that I think is relevant to this question.另外，请不要指向 SQL 注入，我已使用登录详细信息检查是否添加了正确的凭据，我只会发布我认为与此问题相关的代码。

There are a couple of issues with your HTML markup.您的 HTML 标记存在几个问题。 Ie you have a <button> tag inside an anchor <a> tag which is technically incorrect.即，您在锚<a>标记内有一个<button>标记，这在技术上是不正确的。 However, you most likely have some Bootstrap styling on the button tag and are only using the anchor to action the AddToZip.php call right?但是，您很可能在按钮标签上有一些引导样式，并且仅使用锚点来执行 AddToZip.php 调用，对吗？

If that's the case, I would rather strip out the <a> tag and use an onclick method on the <button> .如果是这种情况，我宁愿去掉<a>标签并在<button>上使用 onclick 方法。 An example:一个例子：

Replace代替

<td><a href="AddToZip.php?id='.$row["ID"].'" target="target"><button  id="pdf" name="AddToZip" action="" class="btn btn-primary"><i class="fa fa-pdf"" aria-hidden="true"> </i>Add to Zip</button></a></td>
<iframe style="display:none;" name="target"></iframe>

With和

<td><button id="pdf" name="AddToZip" type="button" class="btn btn-primary" onclick="document.getElementById(\'frame-x\').src=\'AddToZip.php?id='.$row["ID"].'\'; this.disabled = true;"><i class="fa fa-pdf" aria-hidden="true"> </i>Add to Zip</button></td>
<iframe style="display:none;" name="target" id="frame-x"></iframe>

To be clear要清楚

This is not an ideal solution, just a quick fix to achieve what the OP asked for help with.这不是一个理想的解决方案，只是实现 OP 寻求帮助的快速解决方案。 To the OP, I highly recommend using an Ajax call of sorts to communicate to the back-end.对于 OP，我强烈建议使用 Ajax 调用来与后端通信。

I suggest looking into jQuery's AJAX API我建议查看jQuery 的 AJAX API

So now that I see you are using jQuery AJAX calls, add a function to your script section:所以现在我看到你正在使用 jQuery AJAX 调用，添加一个 function 到你的脚本部分：

<script>

$(document).ready(function(){
    ...
};


var addToPdf = function(id, btn) {
    $.get({
        url:"AddToZip.php?id=" + id,
        success: function(data) {
            btn.disabled = true;
        }
    });
};
</script>

Then change your markup to this (remove the iframe as well):然后将您的标记更改为此（同时删除 iframe）：

<td><button type="button" class="btn btn-primary" onclick="addToPdf(\''.$row["ID"].'\', this)"><i class="fa fa-pdf" aria-hidden="true"> </i>Add to Zip</button></td>
